7-3 Warning function
The warning will be triggered before the protective function is activated, and you can check the conditions such as
overload beforehand.
To clear the warning state, perform the same steps as for the normal clearing of alarms.
In addition, when an A-CLR input is in ON state, warning is always cleared.
This function does not support “Warning non-latch mode” that allows clearing of the error and transition to non-error
state in one second after the cause of the warning is eliminated.
Over-load warnings detected by using Over-load warning detection level (Pr6.73) or Over-load warning release level
(Pr6.74) are cleared when the load factor becomes lower than the level appropriate to clearing of the warning. The
warning latch function is not supported.

Over-load warning
detection level
0–114
%
Set the threshold used to detect overload warnings during increase of
overload factor. Use overload factor for the threshold setting.
Setting 0 makes overload warnings detected with the existing condition
(85% of overload level).
Settings other than
“
Pr6.74
≦
Pr6.73 < (overload level)
”
also make
overload warnings detected with the existing condition (85% of overload
level).

Set the threshold used to clear active overload warnings during decrease of
overload factor. Use overload factor for the threshold setting.
Setting 0 makes overload warnings detected with the existing condition
(85% of overload level).
Settings other than
“
